Frequently asked questions
How do I get my Attio Personal Access Token?
Log in to your Attio account, go to Workspace Settings > Developers, and you can create a new Personal Access Token (PAT) there.
What are 'Attributes' in Attio?
Attributes are the columns or fields on an object (e.g., Name, Email, Deal Value). You can list them using the list_attributes tool.
How does 'assert_record' work?
The assert_record tool performs an 'upsert'. It checks if a record with a specific matching attribute (like an email address) already exists. If it does, it updates it; if not, it creates a new record.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
